FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 503,989, dated August29, 1893. Application filed July 14I 1892. Serial No. 440,040. (Nomodel.)

To a/ZZ whom it may concern:

Beit known that I, WALKER A. Sco'rT, of Evansville, county ofVanderburg, and State of Indiana,have invented certain new and usefulImprovements in Folding Beds, of which the following is a specification,reference being had to the accompanying drawings.

The object of my invention is to produce improved mechanism foroperating a foldingbed, whereby a complete and practical bed may be madeat a considerably lower cost than those operated by mechanism now inuse, and which is strong, durable, and easily manipulated.

Referring to the gures of the drawings, Figure 1 shows an inside view ofone side of the frame, illustrating the corresponding operative parts.Fig. 2 shows a diagrammatical View of the operative parts of mymechanism assembled. Fig. 3 is a detail section of the cup shapedprojection 6 and connected parts.

Referring to the figures of the drawings, 1 indicates a frame,preferably made of Wood in any suitable manner, and adapted to receive,as usual in its open front, a folding or bed part 2. The frame isprovided on opposite sides, near its base, with bearings 3, preferablymade of a cast iron plate adapted to be screwed upon the inside of theframe, and provided with a semi-circular ange 4. j

5 indicates a journal preferably consisting of a cast iron plate,adapted to be screwed to the side of the bed part and provided with acup-shaped projection 6. One of the journals is adapted to set into theadjacent bear- The jouring on opposite sides of the frame. nal is madeinternally cup-shaped, as illustrated, for the purpose of givingstrength to the parts, and avoiding friction in the movements of thebearing. Upon oneside the bed part is secured by screws, or othersuitable means, a segmental gear 7, concentric with the journal 5, andadapted to mesh with a pinion 8 projecting inwardly from the adjacentside of the frame.

9 indicatesaspindle, and lOabearing adapted to carry the same in thesideof the frame. The spindle is longitudinally, as well as revolubly,movable in its bearing, and carries on its inner end the pinion 8, andon its outer end the crank 11. a

12 indicates a recess on the inside of the frame, into which the pinionmay be drawn out of engagement with the segmental gear.

13 indicates a latch for holding the pinion in engagement with the gear.It is preferably pivoted at one end, as indicated at 14; and is providedwith a semi-circular recess 15, which is adapted to partially encirclethe bearing' or spindle of the pinion and bridging the recess 12 to holdthe pinion longitudinally fixed.

1G indicates a segmental plate secured by any suitable means to the sideof the bed part, and provided, near its opposite end, with apertures 18,into which a spring-actuated pin 19 in the side of the frame may be setwhen the bed part is in the completely elevated or completely loweredposition to hold it in place.

'The operation of my device is as follows: Thejournals beingsetintotheir bearings, the spindle and pinion are thrust into operativeengagement with the segmental-gear, when by turning the crank in eitherdirection the bed part may be raised. or lowered, as the case may be,the spring-actuated vpin having, if necessary, been first withdrawn fromthe apertures of the segmental plate. When the bedv part reaches theproper position-that is, either the completely raised,or completelylowered position, the spring-actuated pin will immediately enter theproper aperture in the segmental plate and hold the parts fixed. If

lit is desired to separate the bed part from the frame, which must befrequently done for cleaning purposes or the like, all that is necessaryis to withdraw the pinion from engagement with the segmental gear andmove the movable part out of its bearings.

What I claim is- In a folding-bed, the combination with -a frame and amovable part, of a semi-circular flange bearing on the frame, a journalupon the movable part, a segmental gear upon the movable part, alongitudinally movable revoluble pinion carried in the frame adapted tomesh with the segmental gear, or to be separated therefrom, whereby theparts may be operated or separated, substantially as and for the purposespecified.

In testimony of all which I have hereunto subscribed my name.

WALKER A. SCOTT.
